Answer:
Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. ... Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit.
The force of gravity between Earth and Mars will decrease.
The gravitational law is given as-
F = G mM/r²
here, m= mass of rocket
M = mass of earth
r = distance between earth and rocket
So, as rocket takes off from earth and fly towards mars then the distance starts to increase between earth and rocket, and the gravitational pull between them starts to weaken. Then a point will reach when rocket will far from gravity of earth and could probably enter the gravity of Mars.

Answer:
Lymphatic vessels connect to the subclavian veins, which are part of the blood circulatory system and connect to the heart. Their key function is to transport excessive tissue fluid from interstitial spaces throughout the body back to the blood stream.
Explanation:
The lymphatic system works with the cardiovascular system to return body fluids to the blood. The lymphatic system and the cardiovascular system are often called the body's two "circulatory systems."
The lymphatic system consists of all lymphatic vessels and lymphoid organs which include the tonsils, thymus gland, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer's patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.
The cardiovascular and lymphatic are both integral parts of the circulatory system. The cardiovascular system basically moves blood throughout the body. Rather than blood the lymph systems carries a clear fluid called lymph (from Latin lympha, meaning “water goddess”) a fluid containing infection-fighting white blood cells, throughout the body unidirectionally towards the heart. The lymphatic system help rid the body of toxins, waste and other unwanted materials.
Answer:
This is because using a long handled requires less force to the center of gravity and makes it easier to rotate than a short handled spanner
